IMPROVEMENT IN WRlNGlNG-MACHINES.

Specification forming part of Letters Patent No. 132,193, dated October l5, 1872.

To all whom it may concern:

Be it known that I, ELBRIDGE G. W. BART- LETT, of the city and county of Providence andState of Rhode Island, have invented a new and useful Improvement in Wringing- Machines, of which the following is a specification, referring to the drawing hereto attached making part of the same.

My improvement relates to the construction and arrangement of the chute or guide-board i which conducts the extracted water from the rollers back into the tub from whence it came 5 and consists in constructing said chute or guide-board with parallel ends and a pintle or stud at each end to vibrate and slide in suitable ways or guides formed in the upright frame-work of the machine, in a manner to provide for reversing the inclination of the chute or guide-board and hold it in position to conduct the extracted water from the rollers into a tub placed on either side of the same, as may be required.

ln the said drawing, Figure 1 is a vertical section through the central part of the wringingmachine from front to rear. Fig. 2 is a di- `vided section of one of the uprights of the frame, showing clearly the ways or guides in which the chute or guide-board vibrates and slides. Fig. 3 is a view of one of the parallel ends of the guide-board with the pintle thereon.

Similar letters mark like parts in all the fig- The wringing-rollers R R are mounted in two upright stands, E, of a frame in suitable bearings, and with the usual appliances for `'governing the action of the rollers. The guideneath the rollers by the two ends, supporting it on one of two oppositely-inclined surfaces, m n, of an angular recess, A, cut in each side of the uprights E, as shown in Fig. 2, with the uppermost part of the board resting against v one of theuppersurfaces g h of said recess; and in order to secure the guide-board from sliding out of the recess or tilting in the oppo site direction from that intended, I provide a pintle or stud, P, on the end s of the guide board, as shown in Fig. 3, and a deeper groove, S, within the recess, on both sides of the tilting point T, for the reception of the pintle P, by which arrangement the sliding movement of the guide-board is limited to the length of the groove S from one side over the tilting point T to the end of the groove S on the other side thereof. The pintles P, it will be seen, are arranged nearer to one edge, F, of the guideboard than to the other, I, by which the greaterweight of the longer side of the board keeps it in place when this part of the board is down, as shown in Fig. I; but when the board is reversed and inclined in the opposite direction, as shown in dotted lines, the weight of the longer side of the board produces a pinch or binding action between the tilting point T and the pintle in the end vof the groove S, which holds the board in this position securely without the intervention of any special fastening or device for the purpose. Thus it will be seen that by the arrangement of the inclined lsurfaces or ways of the recess A and the groove S with the pintles P on the parallel ends of the guide-board, arranged as described, the guide-board may be inclined and held rmly in position to conduct the water on either side of the rollers, as may be required.

The combination and arrangement of the recess A and groove S with the pintles P and parallel ends of the guide-board, substantially as described, for the purpose specified.
